Dhito vs Spotlight
Last updated
The short answer
For finding files, Dhito wins this comparison and the reason is structural. Spotlight is a lexical index: it matches the literal characters you type, so it returns nothing when your words differ from the file's words, and it does not index what is inside images, audio or video at all. Those are not gaps Apple can close with better ranking — they are what a keyword index is. Dhito indexes by meaning, reads images, and transcribes recordings, all on-device for $4.99/month or $99 once. It also acts on what it finds: apps launch and are matched by what they are for rather than only by name, around 45 local file tools convert, compress and merge the result you just found, and answer rows handle sums, conversions, time zones and colours above the results. What Spotlight still keeps is everything around the edges — Mail, Calendar, Contacts, System Settings and web suggestions.

What Spotlight actually does
Spotlight builds a metadata index of your disk and matches the characters in your query against filenames, file text, and metadata. That design is why it is instant and why it costs nothing: character matching is cheap, and macOS keeps the index warm in the background.
macOS 26 Tahoe gave it the largest upgrade it has ever had — better result ranking, filters by file type and app, quick actions you can run straight from the search bar, and clipboard history. Those are real improvements and worth having. None of them change the matching model underneath.
Where a lexical index runs out
The failure is specific, and it is not a bug. If the characters do not match, the file does not come back.
- Search *"client contract signature terms"* and
Agreement_Acme_Corp_2026.pdfdoes not appear, because "contract" and "agreement" share no letters. - A photo saved as
DSC_0982.jpgis invisible unless you tagged it. Live Text can read words inside an image you have open, and Photos does natural-language search inside your library — neither indexes the loose screenshots sitting in Downloads. - A two-hour recorded briefing is matched on its filename. The audio track is not indexed at all.
- Spotlight can open a 90-page contract. It cannot tell you what the budget cap in section 4 says.
One point of precision, because it gets overstated in both directions: the Spotlight file index is built and stored locally. Spotlight Suggestions is the part that sends what you type to Apple, and it can be turned off under System Settings → Spotlight → Search results.
What Dhito does differently
Dhito runs a local embedding model over your files and stores vectors instead of keywords. A query goes through the same model, and files are ranked by distance in that space rather than by character overlap — which is why a query can find a document containing none of the words you typed. Vector embeddings, explained without the math covers the mechanism.
Three things follow from that:
- Images are indexed by content. A local vision model captions and OCRs every image in the folders you point at, wherever they live on disk.
- Audio and video are transcribed. Whisper runs on-device and the transcript is indexed semantically, so a search lands on the minute of the recording where the topic came up.
- Documents can be questioned. A local LLM answers from the file and cites the page, so you can check it.
All of it runs on your Mac's Neural Engine. No files or queries leave the machine, and there is no account required for search to work.
Finding is only half of it
Tahoe's Quick Actions were the right instinct, and Dhito takes it considerably further. A result you found can be acted on without leaving the window: around 45 local file tools cover images (HEIC to JPG, compress to a size budget, resize, strip EXIF and GPS), PDFs (merge, split, compress, page numbers, watermark, extract text), documents, SVG, audio and any file at all (checksum, Base64, zip, summarise). They are reachable from a result's right-click menu, from a multi-select, from the 🧰 Tools tab, or simply by typing "compress" into the search box.
Two guarantees matter more than the list. A tool never overwrites — every run writes a new file beside the original, and undo is the Trash, so the Finder's own Put Back works whether or not Dhito is running. And nothing is uploaded: every verb runs on the machine.
Above the file results sit around 20 answer rows, which is the one place Spotlight and Dhito now overlap directly. Both do arithmetic and unit conversion. Dhito adds time zones, date maths, hashes, UUIDs, passwords, Base64, QR codes and barcodes, hex colours with a WCAG contrast check, offline dictionary definitions, aspect ratios and currency. Everything but currency is pure local computation; Spotlight's suggestions go to Apple.
The honest trade
Dhito is doing real inference over your files, and that costs something Spotlight does not charge you: time and hardware. The first index of a large library takes hours, because transcribing recordings and captioning thousands of images is genuine work. It needs Apple Silicon and about 1.2 GB of disk for the app and its models. And it is a paid subscription.
Spotlight is free, instant, and already running. If your searches mostly succeed, that is the correct tool and there is nothing to fix.
The verdict
Dhito wins on file search outright — it finds files Spotlight structurally cannot, across documents, images and recordings — and it goes further than finding: it launches apps by purpose as well as by name, runs around 45 local file tools on the result you just found, and answers sums, conversions, time zones and colours inline. Spotlight still reaches Mail, Calendar, Contacts, System Settings and the web, which Dhito never touches. Plenty of people keep Spotlight on Cmd + Space and give Dhito a second shortcut; that is a preference now rather than a necessity.
Who should use what
Your searches come back empty
Dhito
The empty result is structural in a keyword index, so no amount of better ranking fixes it. Semantic matching is the only category that changes the outcome.
You have recordings, screenshots, or scans
Dhito
Spotlight indexes their filenames and nothing else. On-device transcription and image captioning is the largest single capability gap between the two.
You need an answer, not a file
Dhito
Spotlight can open a 90-page contract. It cannot tell you what the budget cap in section 4 says. Dhito answers from the document and cites the page.
You want to launch an app
Either
Cmd + Space is a solved problem and Spotlight solves it. Dhito launches apps too, and matches them by what they are for — “messaging app” finds WhatsApp, Telegram and Messages — which Spotlight cannot do. Run both and give each its own shortcut.
You want to convert or compress what you just found
Dhito
Tahoe added Quick Actions; Dhito has around 45 local file tools, reachable from the result itself or by typing the verb. None of them overwrites the original, and none of them uploads anything.
You type sums and conversions into the search box
Either
Both answer arithmetic and unit conversions inline. Dhito adds time zones, hashes, UUIDs, QR codes, hex colours with contrast ratios and offline dictionary lookups, and computes all of them locally; Spotlight reaches the web for suggestions.
Honest limitations
Where Dhito falls short
- It is not a full command palette. It launches apps, runs file tools and answers calculations now, but there is no window management, no clipboard history, no snippets, no automation, and nothing for System Settings panes or web suggestions — so Spotlight still covers ground it does not.
- Apple Silicon only (M1 or later), macOS 13 Ventura or newer — there is no Intel build. macOS 26 Tahoe is the last macOS to support Intel Macs at all, so this is the platform's direction rather than a gap that will be filled.
- The first pass over a large library takes hours, because transcription and image captioning are real inference work. It is incremental after that.
- Roughly 1.2 GB of disk for the app and bundled models, plus the index itself.
- It costs money — $4.99/month, or $99 once. Spotlight is free, and that difference never goes away.
- It indexes local files and notes. Mail, Calendar and Contacts are Spotlight's strongest ground and Dhito does not touch them.
Where Spotlight falls short
- A keyword index cannot match on meaning, so a query phrased differently from the file returns nothing.
- Loose images and screenshots outside the Photos library are matched by filename only.
- Audio and video contents are not indexed at all.
- It finds documents but cannot answer a question from inside one.
- Quick Actions in Tahoe are a short list — rotate, convert an image, create a PDF. There is no compress-to-a-size-budget, no EXIF stripping, no PDF merge or split, no watermarking, and no bulk run over a multi-selection.
- It matches apps by name only, so a query describing what an app is for — “messaging app”, “screen recorder” — returns nothing useful.
- Spotlight Suggestions sends your keystrokes to Apple unless you turn it off.
- The index can silently degrade, and rebuilding it means an mdutil command or a long wait.
Frequently asked questions
Does Dhito replace Spotlight?
Most of it, and more of it than a year ago. Dhito covers the job Spotlight was never designed for — finding a file when you remember what it was about but not what it was called — and since 0.4.28 it launches apps as well, matching them by what they are for as well as by name, so “messaging app” finds WhatsApp and Telegram. It also answers calculations, conversions and time zones inline. What it does not reach is Mail, Calendar, Contacts, System Settings panes and web suggestions, so most people still keep Spotlight on Cmd + Space and give Dhito a second shortcut such as Option + Space.
Is Spotlight private?
The file index itself is built and stored on your Mac. Spotlight Suggestions, which is on by default, sends what you type to Apple to fetch web and App Store results. You can disable it under System Settings → Spotlight → Search results. Dhito has no equivalent — no query, file, or telemetry leaves the machine.
How do Dhito's file tools compare with Tahoe's Quick Actions?
Quick Actions were the right idea on a short list — rotate an image, convert it, create a PDF, run a shortcut. Dhito ships around 45 verbs: image conversion including HEIC, compression to a specific size budget, resizing, EXIF and GPS stripping, PDF merge, split, page numbers, watermarking and text extraction, document and SVG conversion, audio trimming and joining, checksums, Base64 and zip. They run on a single result, on a multi-selection, or from typing the verb into the search box, and every one of them runs on the machine. A tool never overwrites: the output is a new file beside the original, and undo is the Trash, so the Finder's own Put Back works whether or not Dhito is open.
Did macOS 26 Tahoe make Spotlight semantic?
Not in the sense that matters here. Tahoe brought better ranking, filters, quick actions and clipboard history, and the ranking is smarter about what you use most. The underlying match is still lexical, so a query using different words from the file still comes back empty.
Can I run both without them fighting?
Yes, and it is the setup we recommend. Leave Cmd + Space for Spotlight, give Dhito its own hotkey, and optionally narrow Spotlight to Applications and Calculations under System Settings so it stops trying to be a file browser.
Will Dhito slow my Mac down?
The first index is the expensive part and it runs in the background; you will notice it on a large library. After that it is incremental, picking up new and changed files as you work.
What happens when the trial ends?
Dhito is free for 14 days with no account and no card. After that it is $4.99/month, billed in-app and cancellable at any time with access until the end of the cycle, or $99 once for a licence that never renews.
